Benchmark performance
OpenAI-verified 500-issue subset of SWE-Bench. Approaching saturation in 2026 - most frontier models clear 80%+.
369 real tasks on a live Ubuntu desktop VM: file I/O, spreadsheets, creative apps, settings. The July 2025 Verified rebuild moved to AWS (50x parallel) and fixed 300+ task bugs. The flagship computer-use benchmark.
Held-out, contamination-resistant CLI tasks driven end-to-end in a real terminal. Version 2.1 is the 2026 standard for terminal autonomy.
Harder, contamination-resistant successor to SWE-Bench Verified: real GitHub issues with held-out tests. Where coding headroom remains.
